Aminofunctional polybutadiene with lateral polyether radicals and method for producing same

Abstract

A process for preparing polyether-modified amino-functional polybutadienes involves a) reacting at least one polybutadiene (A) with at least one epoxidizing reagent (B) to give at least one epoxy-functional polybutadiene (C); b) reacting the at least one epoxy-functional polybutadiene (C) with at least one amino-functional compound (D) to give at least one hydroxy- and amino-functional polybutadiene (E); and c) reacting the at least one hydroxy- and amino-functional polybutadiene (E) with at least one epoxy-functional compound (F) to give at least one polyether-modified amino-functional polybutadiene (G). The polyether-modified amino-functional polybutadienes preparable by this process are also provided.
